NDM No.: 87-12-150. C [-;..
· On May 16, 1985, the Federal Emergency Management Agency (FEMA) issued a conditional Letter of Map
-' Revision (LOMR) for the subject proposed project. ~At'that time, the tract was known as the "Lesley Tract,"~
and the technical data to support the reclamation was contained in a report entitled Engineering Report to.
the Dallas County Commissioners Court for the Creation'of Dall~, County Levee Improvement District No.
18, and dated October, 1984. ~'- ' ~'~'' "'."
In OctOber, 1985, the 'Texas Water Commission approved the Plan of Reclamation and subsequently the
Northwest Dallas County Flood Control District was created. Construction (filling of the site and overflow
'swale 'construction) was to commence by October2, :1986, and be completed by October 2, 1988. The project
was now known as the "Riverchase Project." ' ':
In 1987, when the Fort Worth District Corps of Engineers revised the Flood Insurance Studies (FIS) for the
Elm Fork of the Trinity River, construction of the proposed project was well under way, and the proposed
",'" t project was bc____~orated into the HEC-2_ model for the Elm ForJ~. Therefore, the revised FIS for the City of
Coppell reflects the'?Riverchase Project." Enclosed is a copy of the Work Map used by the Corps in this
restudy. The filled area for the Riverchase Project and the overflow swale are shown on the west overbank of
.?- -~ the Elm Fork upstreamof Belt Line Road and the ~outh.,westem Railroad ....

' built" drawing with certification that the fill has been placed to the elevations indicated. I have marked in red.

![~:..,' :!: ;.' It is our understanding that a revised Flood Boundary and Floodway Map (FBFM) will be issued for Coppell
which will show the project as removed from the floodway. We would appreciate a copy of the
